I’ve been building Revenue Calculators, a free browser-based suite for creators, operators and small teams to model profit margin, ROI, MRR, CAC, LTV, ROAS, CPM and break-even scenarios.
The idea is simple: no signup, no spreadsheet setup, just fast calculators for checking business assumptions before spending money.
I’m still early and would love feedback from other founders:
The no-signup approach is a big plus. I think the same idea works well for education tools too, where users usually want a quick result without setting up a spreadsheet. An ATAR score calculator is a good example of a focused tool that can make a fairly complicated calculation much easier for students.
This is useful, but I’d be careful positioning it as “free business calculators” long term. That makes it sound like a static resource page, while the actual value is helping creators and small teams pressure-test business decisions before they spend money.
The stronger frame might be closer to lightweight revenue planning: CAC, LTV, ROAS, margin, break-even, and MRR all answer the same bigger question: “Does this move make financial sense before I commit?”
One thing I’d watch is the name Revenue Calculators. It is clear for SEO, but very descriptive and hard to turn into a memorable product brand. If this grows beyond calculators into decision support for creators/operators, a cleaner SaaS-style brand like Beryxa .com could give it more room than a purely functional name.
